True or False? The reaction equation BaCO3(s)-> [Ba]2+ + [CO3]2- represents an acid/base equilibrium system. In the equation, the arrow is suppossed to be a double one with an arrow pointing in each direction.

False.

The reaction equation BaCO3(s) → [Ba]2+ + [CO3]2- does not represent an acid/base equilibrium system. It actually represents a dissociation reaction, where solid barium carbonate (BaCO3) breaks down into barium ions ([Ba]2+) and carbonate ions ([CO3]2-).

An acid/base equilibrium system typically involves the transfer of protons (H+) between species. In this particular equation, there are no protons being transferred, so it does not correspond to an acid/base equilibrium. Additionally, the notation of a double arrow with arrows pointing in both directions indicates a reversible reaction, indicating that the reaction can occur in both the forward and reverse directions. In this case, a single arrow is used, suggesting that the reaction only proceeds in the forward direction, leading to the dissociation of the solid BaCO3.
